In my opinion, there is nothing to do. If you're a long-term investor and you have a plan, and the plan is still valid, I wouldn't change a thing. Based on a chart of the NASDAQ, there is no indication of a change of trend. The DJIA and SP500 look similar.
My portfolio allocation is: 40% Bonds, 30% Energy Stocks and MLPs, 18% Percent Large Cap Stocks; 10% REIT, and 2% Cash. The portfolio earns about 5.2% of market value in dividends.
Note: My portfolio is heavy in energy because 1) I know the industry, 2) there is good potential on the upside in the next three years, and 3) the dividend earnings are between 4% and 5%. I do not recommend this for everyone. Know what you invest in.
